Yes, not having a fuel filter can cause clogged jets. Especially when you take into consideration that your fuel tank has almost 45 years worth of sediment in it.

Yes the fuel pump is mechanical, it runs off of a lobe on the cam. The fuel pump has a rubber diaphragm that that will eventually wear out.

Can you bring the RPMs up slowly? If you can, then I'm gonna guess you have a vacuum problem that is affecting the vacuum advance on your distributor. If you cannot, then you are not getting fuel into the engine.


The only other thing I can think of, and this is highly unlikely, is a clogged exhaust system.
